Jack Thurston is away and in his place Amy Cooper presents a show devoted to the swashbuckling Trixie Chix, London’s female fixed wheel freestylers. Will Amy and her sit-up-and-beg town bike cut the mustard with the trackstanding, bike polo playing, long skidding, backwards circling Trixies? Find out…

In a special Valentine’s Day edition, sultry Southwark Cyclist Miss Alex Crawford explains why cycling is so good for flirting while love goddess Venus Kamura tells of the fifth annual Reclaim Love ‘happening’ on Saturday 16 February at the Eros Statue on Piccadilly Circus. Over the past few days, all across the bicycling world, there has been an outpouring of love for the inspirational Sheldon Brown who sadly died last weekend. We play a song by Oysterband, Sheldon’s all time favourite band. Plus a heads up for Wheels and Heels, a lovely bicycle fashion show on the evening of the 14th, at Columbia Road from 6pm and a chance to party ’til the break of dawn with the swashbuckling Trixie Chix, on Friday 15th February way up there in Dalston, northeast London. No excuse not to get loved up one way or another this week. Whew!

Earlier this evening I learned with great sadness that Sheldon Brown, the mighty, generous and wonderfully eccentric cyclist and repository of so much bicycle knowledge, has died. On behalf of everyone who helps to make The Bike Show, I extend our deepest sympathies to Sheldon’s family and friends.

In the fullness of time, The Bike Show will produce a proper tribute to Sheldon. If you want to your own memories and thoughts about the great man to be part of that show, then you can leave a video, audio or written tribute using the Comment link at the bottom of this post. It should work with any computer webcam/microphone and there is a preview available before you press ‘send’. Tell the listeners of The Bike Show what Sheldon meant to you and to your life on two wheels.

Private companies and revenue-hungry government agencies have always had a stranglehold on the world’s best maps, until the arrival of Open Street Map, a volunteer-driven effort akin to Wikipedia for mapping and cartography. OSM offers endless customisation possibilities, is entirely open source and in many parts of the world is rivaling the best online and paper maps. OSM’er Andy Allan explains how he’s been adding information relevant to cyclists and explains how anyone can contribute to the project. George Coulouris and Jean Dollimore give a guided tour of Camden Cyclists’ collaborative online cycle route planning tool.
